Bing's mobile web app just got an update for mobile devices that support HTML5 standards, which means iOS and Android. Aside from getting a glossy new UI, location-based search results, and the ability to find apps for the iPhone, Bing Mobile now spits out real-time data too: You can get current transit directions if you're from Boston, San Francisco, Seattle, Chicago, or LA.

In this way, they've outdone Google Maps on the iPhone—Google Maps also shows you transit routes, but it doesn't give you the same real-time information. Now all that's missing is support for the update on Windows Phone 7. [Bing]
